Description

Die Erfindung betrifft eine Befüllvorrichtung und ein Verfahren zum Befüllen einer Behälterwaage, insbesondere mit einer Komnonente.The invention relates to a filling device and a method for filling a Container scales, in particular with one component.

Derartige Verfahren sind bekannt, zum Beispiel als Verfahren der Dosierung mittels mechanischer Elemente.Such methods are known, for example as a method dosing by means of mechanical elements.

Die Zuführung der Komponenten erfolgt mit mechanischen Dosierelementen, zum Beispiel Dosierschnecken oder Vibrationsrinnen. Dazu ist es notwendig, daß oberhalb der eigentlichen Behälterwaage sogenannte Arbeits- oder Tagesbehälter angeordnet werden, die in ihrem Volumen so ausgelegt sind, daß sie mehrere Teilchargen aufnehmen können. Das Dosierorgan in Form einer Schnecke übernimmt somit die Aufgabe des Austragens und Zudosierens der Komponenten und kann in Grob- und Feinstrom betrieben werden.The components are fed with mechanical Dosing elements, for example dosing screws or Vibrating channels. For this it is necessary that above the actual container scale so-called work or Daily containers are arranged in their volume so are designed so that they can accommodate multiple batches. The dosing element in the form of a screw thus takes over The task of dispensing and dosing the components and can be operated in coarse and fine flow.

Diese Konfiguration benötigt einen relativ großen Platzbedarf des Arbeitsbehälters und damit verbunden einen hohen Investitionsaufwand für Behälter, notwendige Austragshilfseinrichtungen und Räumlichkeiten.This configuration requires a relatively large one Space requirement of the work container and associated with it a high Investment costs for containers, necessary Discharge facilities and premises.

Weiter sind derartige Verfahren mit pneumatischer Befüllung bekannt. Such processes with pneumatic filling are furthermore known.

Die Dosierung im Feinstrom ist dabei nicht beliebig klein und exakt zu steuern. Außerdem ist die Waage während der Befüllung teilweise unterschiedlichen Druckverhältnissen ausgesetzt. Darüber hinaus muß sie in der Regel einen Entlüftungsfilter zur Reinigung der Förderluft vom mitgeführten Material aufweisen.The dosage in the fine flow is not arbitrarily small and to control exactly. In addition, the scale is partially during filling exposed to different pressure conditions. In addition, it must be in the As a rule, a ventilation filter for cleaning the conveyed air from the carried material exhibit.

Diese Filterelemente sind bei der Entleerung der Waage immer mit Reststaub gehaftet. Durch diese Faktoren wird die Genauigkeit der Verwiegung negativ beeinflußt.These filter elements are always with residual dust when emptying the scale stuck. These factors make the weighing accuracy negative influenced.

Aus der DE-A 1-2 438 699 (FR-A-2 282 105) ist eine Dosiereinrichtung für pneumatische Förderanlagen bekannt, bei welcher eine Grob-und eine Feindosierung erfolgt. DE-A 1-2 438 699 (FR-A-2 282 105) is a metering device for pneumatic Conveyors known, in which a rough and a fine metering takes place.

Es ist Aufgabe der Erfindung eine Befüllvorrichtung, insbesondere zum Befüllen einer Behälterwaage zu schaffen, welche sowohl eine rasche Befüllung des Behälters, als auch eine genaue Dosierung ermöglicht. Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst.The object of the invention is a filling device, in particular for Filling a container scale to create both a quick Filling the container, as well as an exact dosage allows. This The object is solved by the features of independent claim 1.

Ein entsprechendes Verfahren ist im unabhängigen Anspruch 6 ausgegeben. A corresponding method is given in independent claim 6.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher erläutert. Die Zeichnungen zeigen:

  • Fig. 1 ein Anlagenschema,
  • Fig. 2 eine Detaildarstellung.
    • An embodiment of the invention is shown in the drawings and is explained in more detail below. The drawings show:
  • 1 is a system diagram,
  • Fig. 2 shows a detail.

    • Die Schüttgutkomponenten werden in einer Sackaufgabestation 1 eingefüllt, so daß ein Mindestvorrat an Material, signalisiert durch Füllungsmelder 2, für die Verwiegung bereitsteht. Dazu wird der schwenkbare Deckel 3 der Sackaufgabestation geöffnet und nach dem Befüllen geschlossen.The bulk material components are placed in a bag feed station 1 filled in, so that a minimum stock of material signals through filling indicator 2, for which weighing is available. To the pivotable lid 3 of the bag loading station is opened and closed after filling.

    Während des Befüllvorganges wird durch eine Absaugventilator 4 über ein integriertes Filter 5 die Sackaufgabe aspiriert, so daß auch staubhaltiges Material ohne Staubauftritt aufgegeben werden kann.During the filling process, a suction fan 4 aspirates the bag task via an integrated filter 5, so that even dusty material without dust is abandoned can be.

    Zur Erzeugung des Förderluftstromes wird ein Gebläse 6 eingesetzt, welches über die Klappe 7 auf die entsprechenden Komponenten aufgeschaltet werden kann. Das gesamte System wird über einen Dosierprozessor gesteuert. Zur Befüllung der Waage im Grobstrom wird das Absperrorgan 8 der entsprechenden Komponente geöffnet, die Klappe 7 in der Reinluftleitung geöffnet und das Gebläse 6 gestartet. Zeitverzögert wird die Schleuse 9 gestartet, und der Wiegebehälter wird im Grobstrom mit hoher Leistung pneumatisch befüllt, wobei der Förderluftstrom nicht in die Behälterwaage geführt wird, gleichzeitig füllt sich dabei Stauraum 15, der die Feindosierung mit Material versorgt. Die Triebkraft der pneumatischen Befüllung ist ein Druckgradient.A blower 6 is used to generate the conveying air flow used, which on the flap 7 on the corresponding Components can be switched on. The whole system will controlled by a dosing processor. For filling the scale in the coarse flow the shut-off device 8 becomes the corresponding one Component opened, flap 7 in the clean air line opened and the fan 6 started. The time is delayed Lock 9 started, and the weighing container is in the coarse flow pneumatically filled with high output, the Conveying air flow is not led into the container scale, at the same time, storage space 15 fills up Fine dosing supplied with material. The driving force behind the pneumatic filling is a pressure gradient.

    Bei einer frei wählbaren Gewichtsgröße vor Erreichen des Sollgewichtes wird der Grobstrom durch Abschalten der Schleuse ausgeschaltet und nach einer Nachlaufzeit das Gebläse abgeschaltet. Nun kann durch öffnen der Klappe 16 ein Druckausgleich in der Waage herbeigeführt werden, so daß das gesamte Wägesystem unter atmosphärischen Bedingungen arbeitet. Nun wird abermals die Klappe 8 geöffnet und über das Dosierorgan 14 in Feinstrom soviel Material zugewogen, daß das Sollgewicht exakt erreicht wird.With a freely selectable weight size before reaching the The coarse flow becomes the target weight by switching off the lock switched off and the fan after a run-on time switched off. Now can open by opening the flap 16 Pressure balance in the balance can be brought about, so that the entire weighing system works under atmospheric conditions. Now the flap 8 is opened again and the Metering device 14 weighed so much material in fine flow that the Target weight is reached exactly.

    Dabei wird der Vorabschaltpunkt durch den Wägeprozessor nach jedem Dosiervorgang neu berechnet und optimiert. Nach Befüllung der ersten Komponente werden in gleicher Weise die weiteren Komponenten dosiert und die gesamte Rezeptur zusammengestellt.The pre-switch-off point is adjusted by the weighing processor recalculated and optimized every dosing process. After filling the first component will be the other in the same way Components dosed and the entire recipe put together.

    Die vom Fördergut im Dosierelement 12 getrennte Förderluft ist staubhaltig und wird durch Rückführung in die Sackaufgabestation 1 über deren Filter 5 abgereinigt.The conveyed air separated from the conveyed material in the metering element 12 is dusty and is by recycling in the Bag loading station 1 cleaned through its filter 5.
